Systematic investigation of geometrical parameters' influence on the appearance of surface deflections in sheet metal forming

A Weinschenk, W Volk - Journal of Physics: Conference Series, 2016 - iopscience.iop.org
Surface deflections occur during springback, which follows deep drawing. They highly affect
the visual appearance of outer skin components and are, therefore, undesirable. In this …
